The low-rank structure reverberation suppression algorithm is a better method to restrain the sea interface reverberation. But the data processing speed of the method is very slowly due to the complexity of singular value decomposition. It can not meet the real-time requirement in actual application. This article present a signal subspace fast approximation method based on unitary transformation which...
To simulate the human decision-making in steering to follow a planned path, we modeled the driver's learning process by using an idea of target position. The proposed model dealt with the driver's decision-making mechanisms in tracking a target position by means of Cloud Neural Network. Results from the simulation of lane changing showed the capability of the proposed model to simulate a driver's...
Learning and memory, which are important functions of the human brain, are the foundations of thinking. Revealing the learning and memory mechanism of human brain is the core objective and main development way of the intelligent science. Improved human brain functional structure model, a memory prediction structural framework on the brain structure and function are proposed. And then we work out a...
Agile manufacturing cells can be considered as the logic combination of physical resources in the shop floor. Compared with fixed cells, they are more competent to adapt rapidly to changes in production environment. To fulfill the idea of agile manufacturing cell in shop floor production management, the cell reconfiguration problem should be settled firstly. According to general principles on cell...

Aimed at the parasitic oscillation phenomenon existing in rectifier output of DC-DC converter, a new symmetrical RCD clamp circuit is designed to suppress the voltage spike and reduce the energy loss, while achieving switching inverted in zero-voltage. The main circuit topology is given, in the same time, a detailed analysis of the clamp circuit working principles, characteristics and parameters of...
Error model customization for different work type of complex CNC equipments is significant to identify and compensate the errors of CNC integrated manufacturing, and further to achieve process optimization and product quality control. Traditional error modeling method is complicated, takes long time and is difficult to change itself. A flexible customized error modeling method based on feature and...
In this paper, a fuzzy logic system for metal analysis in a basic oxygen furnace (BOF) is described. This system uses the optical spectral emitted from the BOF mouth as inputs and the carbon content of the molten metal contained in BOF as outputs, in order to provide an efficient decision support application. The membership functions and the rules are defined by utilizing both data analysis and expert...
Through comparing and analyzing the existing digging shovel of cassava machinery, and based on the physical characteristics of soil, cassava tuber and the standard factors of the traction power, a triangular convex shovel was designed. Shovel blade angle is 106°, blade width is 100cm, shovel face tilt angle is 25°, the terminal height of shove is 20cm, shovel length is 30cm and of finger-like extension...
